VASCULAR PROSTHESES STRAIGHT AND BIFURCATED

Technical characteristics of TRICOGEL® grafts
TRICOGEL® grafts are composed of :

·        Knitted polyester double velour vascular prostheses ;

·        Porcine gelatin.

The two elements are bonded by surface adhesion.TRICOGEL® grafts are 
characterized by:

·        light yellow color ;

·        intraoperative tightness – no preclotting ;

·        hydrophilia which can be observed as an instant moistening of the surface with patient’s blood and as sweating. The blood stream does not dissolve nor washes away the gelatin but causes the gelatin film to swell, which makes a better tightness.

·        antithrombogenicity – a coat of networked gelatin is hemocompatibile until its complete biodegradation and does not activate any platelets,

·        rigidity when dry, which fades after contact with liquids (blood) ;

·        high mechanical strength ;

·        elasticity and prevention to stretching and bending the gelatin film which take place when the graft is taken through the canals in the abdominal cavity; 

·        low mass ;

·        no fraying and easy handling ;

·        clear marking line.;

·        TRICOGEL® grafts are prestretched and sold as a sterile biomaterial.

SERILIZATION

Grafts are sold as sterile. Colored marker on the package inside the box indicates radiation sterilization performed on the material. The marker darkens under radiation. Grafts cannot be resterilized.Sterility period guaranteed by the manufacturer is 3 years.

SUTURING THE ANASTOMOSES

It is recommended to suture TRICOGEL® grafts with synthetic, non-resorbant, polyester or polypropylene sutures using atraumatic semicircular needles. Sutures 3-0 are recommended for suturing and aortic anastomoses and brachiocephalic trunk, whereas sutures 4-0 ought to be used for suturing iliac arteries. 

TRICOGEL® prostheses are prestretched and sold as dry, sterile biomaterial. It is not recommended to fix clamps on a prosthesis except on the edges to be cut off.

STORAGE

TRICOGEL grafts ought to be stored in airy dark rooms in conditions preventing wetting and damaging, either mechanical or chemical.
